I scored a set of Hot racing AX10 High Steer Knuckles from my mate Pete .They look about the same as the axial ones in shape and form.
The installation went fine although at first i was planing to install the link above the hole , but it was interfering with the servo horn .
After a bit of cutting of threaded rods and  bending i mocked up the new steering links . i bent them in the vise . There is a bit of toe out to combat the Ackerman at full lock.
This is probably as much as an angle i can get without the XR mod , i had to back up the steering end points a bit to stop the tires from hitting the shocks.
